Air flow is an important factor needed to be considered in architectural designs where perforated metal come as an ideal mesh material. The perforated panels used for building air flow control are called perforated diffusers or air diffusers. It is used as ceilings or roofing panels.

Reasons to Choose Perforated Metals as Roofing Diffusers:

The perforated panels has slotted holes to make it light in total weight and enable the air flow and light flow. At the same time, the holes and openings can be square, round, hexagonal and decorative to meet the whole setting style of the architectures.
